Merry Christmas! I've had the Sony X850E 75" now for about a month. Really like it. This afternoon when watching the Youtube app. Went back and hit the TV button to watch OTA antenna TV. The picture suddenly went on the fritz. Extremely off colors and bright blotches. Went back to Youtube and Netflix and it didn't fix it. Turned the TV off. Turned it back on and the OTA antenna signal did it again. Have the HDMI hooked up to a Sony receiver for audio. Later turned it back on. Now it's not doing it. What concerns me is that more than likely it will eventually do it again. Has anyone else had this problem?
